Abstract: This invention is concerned with materials for nonlinear optical devices for the conversion of optical energy at one frequency to optical energy at another frequency. 
<??>Laser techniques have been developed to a great extent and it is possible to obtain various kinds of laser light by utilizing solid, gas, and liquid media. Laser light having various wavelengths is often desired and in some cases, a laser light exhibiting a continuous spectrum over a certain range of wavelengths is desired. One means for converting coherent laser light of a fundamental frequency into laser light of a wavelength having a frequency twice the fundamental frequency (i.e., the second harmonic) involves passing the laser light through a nonlinear optical crystal. 
<??>This invention involves devices for and method of generating coherent second harmonic light radiation. The devices comprise a laser source of coherent light radiation at a fixed fundamental frequency, a Schiff base compound, means for directing the output radiation of the laser onto the Schiff base compound, and output means for utilizing the second harmonic frequency. Preferably, one moiety of the Schiff base compound has a hyperpolarizable group and the other moiety of the Schiff base compound has a configuration so that the compound crystallizes in a non-centrosymmetric configuration.

Abstract: A dynamic frame length slotted ALOHA communication system has a central station which monitors the traffic congestion and determines the optimum frame length. This is transmitted to the sub-stations in the form of a service information message when there is to be a change in the frame length but not, as is conventional, at the beginning of each frame. The amount of time available for the useful transmission of communication messages is thus optimised.

Abstract: This printed circuit board (200) with optical signal distribution layer (101, 102) uses a layer of transparent material or an optical fiber mat build into the laminated printed circuit board structure to interconnect various opto-electrical devices (110,111) which are attached to the surface of the printed circuit board. 
     The optical devices are connected to the buried optical fiber layer by drilling vias in the printed circuit board to intercept the fiber or the particular optical signal distribution layer at a desired location. The via is then filled with an optical material (210) whose optical properties provide for the coupling of light energy from the intercepted optical signal distribution layer through the via material to the surface of the printed circuit board. Opto-electrical devices are connected over the top of these vias and perform the optical light energy to electrical signal conversion function.

Abstract: A photographic copying apparatus for reproducing an image of an original on a sheet of photosensitive paper. A roll of photosensitive paper (S) mounted in a magazine (27) is fed downwardly and cut into sheets. Each sheet is sucked to a vertically arranged suction conveyor (22) and fed down. When it reaches a predetermined position, the feed of the sheet stops. An exposure table (1) which is turnable and movable between two points is turned to its upright position and pressed against the sheet on the conveyor. In this state, the suction conveyor stops sucking the sheet while the exposure table starts sucking it, so that the sheet is handed over to the latter. The table now carrying the sheet moves toward the other end for exposure. On its way, it is turned to bring the sheet carrying side up and passed under a corona charger (54). As the table reaches the other end where there is provided an exposure unit, it is turned again to an upright position. In this state, the light reflected by an original is shed on the sheet for light exposure. The table is then turned to bring its sheet carrying side down and moved in an opposite direction toward the conveyor. On its way, the sheet is brought into contact with one of several kinds of developing solutions in tanks which are adapted to be raised into contact with the sheet one after another.   Any excess solution applied to the sheet is then removed by a squeezer (58). After this first development cycle, the table is turned by 180 degrees and moved toward the exposure unit again for another cycle of development. This cycle is repeated as many times as the number of colors used.

Abstract: The invention relates to a voltage multiplier, comprising a series connection of rectifier elements which are alternately rendered conductive by alternately applying complementary clock signals to capacitances which are connected to junction points of pairs of neighbouring elements. The rectifier element is constructed by means of field effect transistors so that the well in the substrate in which the element is realized receives either the anode voltage or the cathode voltage. This prevents the occurrence of the so-called back-gate bias effect which increases the threshold voltage of the element and limits the output voltage of the voltage multiplier.

Abstract: A sheet feed apparatus for a copying machine comprises a cassette (25) for holding a stack of sheets (26) to be fed. The cassette is in the form of an open-topped housing (45) containing a base plate (40) for supporting the stack of sheets (26). A handle (47) is provided which is coupled to a mechanism (50) for raising, preferably tilting, at least part of the base plate right out of the cassette housing to facilitate loading sheets within the tight tolerances of the cassette housing. A rear registration guide (41) and a pair of relatively small side guides (42) are provided which do not impede stack loading but allow the stack to be positioned sufficiently accurately that when the handle - and hence the base plate - is lowered the stack is able to enter the cassette housing without further adjustment.

Abstract: A retractable, partial eyeshield assembly is attached to a single eye sighting device attached to, for example, a video camera. The partial eyeshield assembly is constructed so that it covers a portion of the medial field of view of the user's nonsighting eye. The obstructed portion of the nonsighting eye's medial field of view corresponds to that portion of the sighting eye's that contains only the image transmitted through the single eye sighting device's sighting aperture. By obstructing the portion of the nonsighting eye's medial field of view, the corresponding field of view in the sighting eye dominates. The obstruction of the portion of the nonsighting eye's field of view is achieved without obstructing a substantial portion of the nonsighting eye's peripheral and medial fields of view.

Abstract: There is provided a digital data recording system in which digital data which is encoded by the RLL (Run Length Limited) encoding system in which code "1" does not continue is recorded onto a recording medium in accordance with an NRZL (Non Return to Zero) rule. In this system, the digital data is input, a width (T) of pulse corresponding to code "1" in the input digital data is converted into a pulse of a width (T′) larger than the pulse width, and the digital data of the converted pulse width is recorded onto the recording medium. A change amount of the pulse width is made different in accordance with the minimum number of codes "0" arranged between codes "1" and "1" in the digital data. With this system, the error rate of the digital data recorded on the recording medium can be reduced. In the case of the same error rate, the recording density can be improved.

Abstract: A read/write memory has bit line pairs variously having a first or a second true/complement orientation. Data is selectively coupled to and from the bit line pairs to and from a data line pair via a column decoder. The memory has redundant bit line pairs aligned in the first true/complement arrangement. When a redundant bit line pair is implemented, the logic state of the data is inverted both for reading and for writing if the replaced bit line pair is of the second true/complement orientation. This results in the voltage impressed onto the memory cell for a given logic state is the same for the redundant bit line pair as for the bit line pair that it replaced.
